| Title | |
| Description | The inspectors identified a noncited violation of Technical Specification 5.5.1.1 for the failure of maintenance personnel to have adequate procedures in place to ensure maintenance associated with a saltwater cooling isolation butterfly valve would not adversely impact the availability or operability of the component cooling water heat exchanger. Specifically, on January 8, 2008, inadequate procedures resulted in the failure to properly install butterfly Valve 2HCV6510. Additionally, the postmaintenance testing procedure was not adequate to verify the proper function of the valve prior to its return to service. This finding was entered into the licensees corrective action program as Action Request 0806000104. The finding is greater than minor because the degraded saltwater cooling valve is associated with the equipment performance attribute of the Mitigating Systems Cornerstone and affects the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using the Manual Chapter 0609, Significance Determination Process, Phase 1 Worksheets, the finding is determined to have very low safety significance because the finding did not result in a loss of safety function of component cooling water Train A for greater than the Technical Specification allowed outage time. This finding has a crosscutting aspect in the area of human performance associated with resources because the licensee did not have complete, accurate, and up-to-date procedures H.2(c) (Section 1R19) |
